IMPROVEMENTIN MACHINES FoR MAKING Boxes FoR LEvAToRs.

Speciiication forming part of lLetters Patent No. 131,648, datedSeptember 24, 1872.

To all lwhom it may concern:

Be it known that I, WILLIAM L. YOUNG,

' of Marthasville, in the county of Warren and JState of Missouri, haveinvented a new Improvement in Machines for Making Boxes, of which thefollowing is a specification:

rvMy invention 'consists of certain arrangements of apparatus in onemachine, whereby I am enabled to perform all the special operationsrequired to make conveyer-flights by power machinery, and govern eachparticular operation by a standard gage, so that the flight will be muchmore uniform in respect of thev dimensions, and finished better thanwhen done by hand, besides being made very much cheaper.

`Figure 1 is a plan view of the machine, showing the arrangements ofapparatus for beveling the corners and one side of the flights; also forforming the tenons. Fig. 2 is a sectional elevation taken on the .lineoo so of Fig. 1. Fig. 3 is 'a side elevation of the jointingdisk and thesupports for holding the blanks for beveling the corners. Fig. 4 is afront elevation of the cutter used for beveling the side of the longstrips from which the blanks are cut to form the backs of the slats.Fig. 5 is a plan view, and Fig. 6 is a section, of the holder of thestrips when being dressed by the cutter, Fig. 4. Fig. 7 is a plan of ablank for two flights, showing its condition preparatory to forming thetenons and then separating completed flights; and Fig. 8 is a plan ofthe back of a completed flight.

Similar letters of reference indicate corresponding parts.

i I take long strips of wood, previously prel pared in any suitable way,as wide as the widest part of the flights and a little thicker backofthe flights. This block is mounted on the carriage merelybecause acarriage is used for anotheroperation, which will be described furtheron, and because it is not desirable to remove the carriage; but saidcarriage is stationary while the strips are being planed, they beingpushed along the groove A by hand, one after another. B is detachablyconnected to the carriage by an under-cut or dovetail-shaped groove inthe bottom and a correspondingly-shaped seat, G, on the carriage, onwhich the bed is moved endwise in putting it on or taking it off. Theobject of having the bed detachably connected to the carriage is to beenabled to remove it readily and put on another holder for the blanks toperform another operation on them by another cutter-head on the mandrelB, and thus utilize saidrnandrel and other adj uncts for two purposes.The strips, after beingdressed, as above described, by the cutter C, aresawed into lengths adapted for two blanks by any suitable sawingapparatus, and they are presented at their corners to the cutters H ofan edging device in oblique gages K, first one side up and then theother, and at wboth ends, to dress olf all the corners L of the blanks,as clearly indicated in Figs. 1 and 3. Then the back side of each end ispresented to said cutters again in the gage M to form the bevels N.Stops L are provided with the gages K K to regulate the amount to be cutoff the corners.

Then the blanks are clamped in a frame of from which the cutter C will,at this time, have 4 been removed. Thefblanks, being in this mannersubjected to the said cutter-head, will have the shoulders h and oneside of the tenons formed, and the connected tenons of the two will besawed half off by the middle saw, which is larger than the others. Then,the frame being taken off, turned over, and again pushed along under thesaws, the other shoulders, h, and sides fi of the tenons will be formed,and the two blanks will be cut asunder and the batch completed. Thisframe for holding the blanks is secured ou the carriage E by the plate Kand button c'.

The said bed Having thus described my invention, I claim as new anddesire to secure by Letters Patent-J 1. The combination of the guides K,stops L', gage M, and cutter H I, constructed as and for the purposedescribed. 2. The combination `of the cutter-head (consisting of theouter saws e e and a middle saw,

f, projecting beyond the others) and the cut ters g g with theholding-clamp frame a a b b, all constructed as and for the purposedescribed.
